I agaonized about a what new car to buy after losing interest and patience with MB. Looked at Jag Super V8, A8 but the 750 was miles ahead of either. The iDrive is a joy and it makes you question the capabilities of current auto journalists who have not gotten used to this in the past 5 years. Love the power, space and most of the features. Extremely comfortable on any road surface. The car just looks great and does everything the way a car should. The power rear seats are a must and the rear DVD system is great on trips. The car has been totally flawless up to this point and everyone who sees it is impressed and curious.
The exterior and interior styling. The comfort and adjustability of the seating. Great stereo. The car is just very impressive in all areas.
The fact that you have to manually turn on the front parking sensors (unless you engage reverse first) is just dumb. I would like to see more "personalizing" features such as locking preferences and lighting preferences be available through iDrive.
